My research concerns the theoretical foundations of topological data analysis (TDA). Work done in the last several years on theory and applications of TDA has demonstrated that TDA offers a principled, flexible, and computationally viable framework for studying coarse-scale global geometric features of data [17, 26, 13, 7, 11, 10, 8, 24]. Moreover, the tools of TDA have proven to be very well s...

My research lies in the area of Natural Language Processing (NLP), a highly interdisciplinary field of study comprising of concepts and ideas from Artificial Intelligence, Linguistic Theory and Statistics. Naturally occurring instances of human language, be it text or speech, are growing at an exponential rate given the popularity of the Web and social media. In addition, people are increasingl...

A 67-year-old man with a three-year history of non-scarring alopecia that progressed to alopecia totalis despite intralesional glucocorticoid injections is presented. He developed 20-nail dystrophy that was recalcitrant to antifungal and anti-inflammatory treatments. Biopsy of the nail matrix showed histopathologic features of lichen planus. Alopecia totalis and isolated lichen planus of the na...

One possible consequence of ICT’s rapid rise will be a new ‘generation gap’ arising from differing perceptions of the learning technologies. The nature, causes and consequences of this gap are of interest to educational practitioners and policymakers. This paper uses data from an ongoing project together with a synopsis of research to describe the ICT-based generation gap that currently exists ...
